ANTIRATELE KEY RING.

Application filed N ove n ber 7, 1923. Serial 1Tp.,73,23.

To all ii/10m it may concern Be it known that I, LEWlS P. DUCI-IENE, a citizen of the United States, residing at iloodlawn, in the county of Beaver'and State of Pennsylvania, have invented certain new and useful lmprovements in Antirattle Key Rings, of which the following is a specification.

This invention relates to an anti-rattle key ring and while primarily intended to serve as a carrier for keys employed in connection with the operation of motor vehicles, namely, ignition key, transmission key, tire key, tool-box key, door key, etc., it is to be understood that the device may be used for any other purposes wherein it is found to be applicable.

The primary object of this invention is to provide a key ring, of the type stated, which will entirely eliminate the annoyance occasioned by the rattle of a plurality of keys attached to a common carrier when the ignition key is in use, due to the vibratory movement of an operating motor vehicle.

Further objects of the invention are to provide a device of the character described, in a manner as hereinafter set forth, which is simple in its construction and arrangement, strong, durable and etficient in its use, compact, attractive in appearance and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangementof parts hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the principle of the invention.

in the drawing forming a portion of this specification and wherein like numerals of reference designate corresponding parts throughout the several views Figure 1 is a prespective view of an antirattlc key ring in accordance with this invention and carrying a plurality of keys.

Figure 2 is a side view of the device with the spring in the compressed position.

Figure 3 is a. side view of the annulus with the fixed stop disk mounted thereon.

Referring in detail to the drawing 1 denotes a metal annulus provided with an opening 2 to permit of the mounting of keys 3 thereon in the usual manner.

A s nall disk l is mounted on the annulus 1 and is permanently fixed to the latter, by soldering or in any other suitable manner, at a point approximately one-third of the .way around from the opening 2, of the annulus 1, as cliflfly shown in Figure 3, of

the drawing.

A spiral spring 5 is mounted on the annulus, 1, and has one end thereof fixedly secured to the fixed disk 4. The other end of the spring 5 is attached to a corresponding disk 6 which latter is shiftably mounted on the annulus 1.

The spiral spring 5 is capable of compression to allow the shiftable disk 6, carried on the free end thereof to clear the opening 2 in the annulus 1, as shown in Figure 2 of the drawing. When the spring 5 is in such compressed position, the keys 3 may be mounted on the annulus 1 in the usual manner. Upon release of the spiral spring 5 its expansion will force the shiftable disk 6 against one side of the adjacent key while the side of the first key will abut against the fixed disk 4, as shown in Figure 1, of the drawing.

As one end of the spring 5, with the disk 4, is fixed to the annulus 1, the spring 5 cannot shift around as a whole on the annulus 1, thereby preventing the keys 3 from shifting to the opening 2 in the annulus 1, and become detached therefrom.

The action of the spring 5 against the keys 3 in the manner described, will hold the latter firmly in position and thereby prevent rattling which accompanies a plurality of keys dangling from the ordinary key ring.

From the foregoing description taken in connection with the accompanying drawing, the principle of construction and method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while describing what is now thought to be the best embodiment thereof. it is to be understood that the device shown in the drawing is merely illustrative, and that various changes in the form, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, which come within the scope of the claims hereunto appended.

\Vhat I claim is:

1. An anti-rattle key ring comprising an annulus formed with an opening and adapted for the reception of a plurality of keys, a spiral spring mounted on said annulus, one end of said spring fixed to said annulus and the other end of said spring loose on said annulus, said spring capable of contraction to clear said opening, substantially as described and for the purpose set forth.

2. An anti-rattle key ring comprising an annulus formed with an opening and adapted for the reception of a plurality of keys, a spiral spring mounted on said annulus, an abutment disk fixed to each end of said spring, one of said disks fixed to said annulus at a point remote from said opening, and the other of said disks shiftable on said annulus, said spring capable of contraction to permit of-said shiftable disk to clear said opening and further capable of expansion to engage said fixed disk, substantially as described and for the purpose set forth.

3. An anti-rattle key ring comprising a resilient annulus formed with an opening and adapted for the reception of a plurality of keys, a spiral spring mounted on said annulus, a fixed stop member mounted on said annulus at a point remote from said opening, a shiftable stop member mounted on said annulus, said spring positioned intermediate of said stop members, said spring member capable of contraction to permit of said shittable stop member to clear said opening and further capable of expansion to cause the engagement of said stop members with each other, substantially as described and for the purpose-set forth.

In testimony whereof I affix my signature.

LEWIS P. DUCHENE.
